Vitamin A supplements

Half of the 5,772 vitamin A supplements in the NIH label database that print an amount list 4,000 IU or less per serving; the middle half list 2,000 IU to 5,000 IU (DSLD version 9.4.0, January 2026). The 124 products whose only supplement ingredient is vitamin A list a median of 25,000 IU.

How much vitamin A do supplements contain?

The median product lists 4,000 IU per serving. One in ten lists 667.1 IU or less, one in ten 10,000 IU or more. The amount printed most often is 5,000 IU (1,259 products).

Which forms of vitamin A do labels name?

Beta-carotene is the form named most often: 5,517 of the 11,596 vitamin A products (48%), ahead of retinyl palmitate (2,967, 26%) and retinyl acetate (1,532, 13%). A product naming two forms counts in both; the table below gives every form.

• Beta-carotene
• Retinyl palmitate
• Retinyl acetate

Which products list the most vitamin A?

On-market products, per serving, with a plausible amount: the rule leaves out likely entry slips, such as an amount far beyond every other label with no %DV or strength on the label to back it (each product page still shows its own amount, marked).
